I'm also considering to have support for several parsers. It should be
pretty simple / straightforward to do so.
We could have a default parser based on INI files and then allow people to
specify a different parser in case INI files are not what they want to use.
I'll dive into libconfig and pick things from there as well.
Also, I agree INI files could be a bit limited, which is why we ended up
having our own INI parser in oslo.config.
